The Schedle rei'en'ed to in these Letters Patent and makhg partof the same.

To all 'whom it'may concrn Be it known that -we, WILLIAM smu; and J o- E GFIISHVER, of Toledo, in the couuty of Lucas and in the State of Ohio, 'have invented certain new .and useful Iinprovements in Grain-Ooolers and Driers;

and do hereby declare that thefollowing is a full,

clear, andexact description thereof, reference being cheap,

Like 'letters deuote like parts in each figure.

The object of our invetion is the construction of bins for the cooling and drying of grain in a simple,

and effective manner by the employment of currents of air; and

` Ourinvention consists iu the adj ustable ventilated screen and funnel of novel construction, through which the grainpasses before it enters the bin; ,in the construction and arrangement of the ventilating-pipes within the bin; iu the construction and arrangement of the shell of the bin; and in the construction and arrangement of its several parts, all as more fully hereinai'ter described. v

Iu the drawing- A represents the shell of the bin, constructed of suitable materials, and separated, by a close vertical cross-partition, a, into'two nearly equal part s, B and O. This shell A is inclosed upon all sides except the c'entrally from end to end by a longitudinal section on the line plank or beam, b. p

A metallic pipe, D, enters one end of the wall of the shell at a point about one-third of the distance from the bottom tothe top; thence proceeding, in the same vertical and horizontal planes, to'a point near the partiton a thence turning at right angles and running directly upwardby the' side of said partition to the top of the` bin, where it ente's a similar pipe, E, which runs along the top of the bin in planes par allel to those of the pipe D.

From a point near the center of the pipe Da hranch, F, runs directly` downward nearly to the bottom of the bin B, where it enters the center of another pipe, G, which extends across the bottom of said hin from side to side at right angles with the line of direction of the pipe D. The ends of this pipe G are provided with perforations c. The pipe D is also provided with globular enlargements H bn each side of the branch pipe F, which enla'gements are perforated on all sides with suitable opeuings d. The vertical portion 'of the' pipe D is provided with a suitable adjustable' valve, I, near its upper end,`and the valve, I near its outer end'.

v From a point near the top of the-vertical portion of the pipe D, and between its valve .I and the pipe E, another pipe, D', extends over the top of the partition a into the bin O then turns down at right augles,

running by the side of said part-ition to a point within said bin coincident with the pipe D; then turns again at right angles, and in the same planes as those of the pipe D, and runs through the bin G and' through the outer wall of its shell;

This pipe is, like the pipe D, furnished with a suitable adjustahle valse, P, placed near the up'per end of its vertical portion, and with globular perforated enr largementsH' placed upon its horizontal portion in similar positionsto those placedonthe pipeD:

I into-the inner end of. the pi pe E a short pipe, K, at tached to a hollow joint, f, enters, which joint 'is capau ble' of lateral movement To the upper-part of this joint a pipe, L,is attached,

provided with a suitable adj ustable valve, 1 This pipe cnters into and is Secured .tothe screen M, upon which the funnel N is placed, and' terminates within said screen in a globular perforated enl'argement, 0.7

The screen M, which is hollow, open at each end, and

provided with perforations in its bottom, is hemispherical in a cross-section, with theflat side uppermost, and is Secured to the pipe L at an inolination of'aboutthirty degrees from a horizontal plane, with its outer end elevated, and

sloping inwardly toward the center-of the bin.

Attached to' the top of this screen is thefunnel N, the bottom of which opens into the interier. of the screen at a point a little outside of the globular' end O of the pipe L.

'A couple of hollow til'e-columns, P and P', provided with suitable perforations g, extend vertically from the under side of the beam b to the bottom of the hin C, which has holes through its bottom correspond-in g with the openings in 'the bottoms' of said tile-columns P and P'. Thecoluuins .are placedat about equal dis tances from the center of the bin 0, and from the partition a and the inner walls of the bin.

A fleXible pipe, Q, provided with =a metallic end, R, of a size proper to fit into the ends of the pipes D D', E, Gr, and K, which are all alike in size, has at its outer end aperfo'rated nozzle, S. The length of this pipe is sufficient to enable it toi-each to any part of the hine B andO, and its nozzleuis made as long as can be Conveniently handled.

The lengthof the removable pipe L s such that it will permit the screeuto rest upon the side walls oi' me h WILLIAM STARK AND JOSEPH Gr. FISHER, OF, TOLEDO, OHIO.

pipe -E with' a similar i .inches will 'be found suflicient. The same remark applies to the tile-columns P and P', of which a diameter of eight or ten inches will be' found suitable for such bins as those above named.

Having thus described the Construction of our graindrier and cooler, the uses and operation of its several part-s are as follows, viz:

The object of two bins, B and C, is.for the reception of 'grain of different degrees of leat or moisture, orof different descriptions of grain' requiring different treatment in drying and cooling, the bin C being for the grain -whicl is dampest. The screen M is so placed that its inner end shall project a little over the bin d'esigned to be filled, while the remainder of it shall pro ject over the outside of the bin. A suitable blower is employed, having a flexible pipe, which will fit into the ends of either of the pipes D D', E, G, orK.

The grain for the bin is received through the funnel N. If the grain is dry, and simply dusty, the. blast is received through the pipe E, and, passing through the screen M, causes all the grain, as it falls into said screen, to be submitted toa current of air, the force of which may be 'negulated by the vnlves I' and 1 I which blows all the dirt .out 'through the outer open end of said screen, while the grain slides into the bin through the inner open end. In this operation the heavier particles of sand may fall through the perforations in the' L ttom of the screen.

When gra-iu which is a little heated or damp is being received through the tunnehas before described, the valve. 1 is closed, and the air-pipe is attached to the outer end of the pipe" D, or toeither end of the pipe G, (in which last instauce the opening at the end of -the pipeD should be closed iu any suitable way,) and the current of air should he allowed to pass through the pipes G F D, a portion escaping through the perforations d and o in said pipes, and the remainder out through the pipe L 'and the screen M.

In like manner, when the grain is being received into the bin O, the air-pipe may be attached to the outer end of the pipe D, and the operation proceed as before.

When either bin is filled and it is desirable to dry and cool the graiu still more, the valve 1 should be closed, and the whole force of the blast expended in one or both of the bins, or in either alternately ;and the blast may be applied at the open end oi' either of the pipes, all the other open ends being closed.

The object of the flexible tube Q is to apply it to the pipe E, so thatthe current of air passing through it may, by means of the nozzle S thrust into the grain, be directed into the corners of the bins, and into those places where there seems to be the greatest heat or dampness.

The object of `the tubular columns P and P' is, in part, to receive 'constantly some portion of the air hen the screen and' funnel are not iu use in receiving grain they may be placed convenientl and secu'ely upon the plank or bearri b.

and method of operation of om' device,

The arrangement .within the bins B O of the pipes D D' 'E F G, provided with valves I I P, and globular enlargenents H and H', and perforationsc and d, substantially as described and shown, for the' purposes set forth.

3. The conbination of the screen M and the pipe E, substautially as described and shown, for the purpose set forth.

4. The combination of thesar-een M and the pipes E, D 1)', F, G, K, and L, substantially as described` and shown, for the purposes set forth.-

5. The arrz-ngement of the bins B and O, the partitiou a the beam b, the pi'pes D D', E, F, G, and K, and the perforated tile-columns P P', substantially as described and shown, -i'or the purposes set forth.`

In testimony that we claim the iforegoing we have hereunto set our hands this 22d (lay ot' October, 1870.
